Watch your language. Words mean different things to different people – so the brainwaves they provoke could be a way to identify you.
Blair Armstrong of the Basque Center on Cognition, Brain, and Language in Spain and his team recorded the brain signals of 45 volunteers as they read a list of 75 acronyms – such as FBI or DVD – then used computer programs to spot differences between individuals. The participants' responses varied enough that the programs could identify the volunteers with about 94 per cent accuracy when the experiment was repeated.
When you start talking about cosmic measurements, most people have a hard time truly comprehending the figures involved. They become abstract, conceptual -- so much larger than any human experience.
So the age of the universe just seems like a number, but it's a very big number: roughly 13.8 billion years. That means the "edge" of the universe is 13.8 billion light-years away -- so far away that we've never been able to observe it.
Canadian researchers are reporting the discovery of a "reset" switch for our body clocks that operates at the molecular level, a finding that could lead to treatments for conditions linked to disruptions of our circadian rhythm.
The discovery could yield a better understanding of a number of disorders linked to such disruptions, from sleep disturbances to behavioral or metabolic problems common with jet lag or shift work, they say.
In our culture, reproduction is often seen as women’s work. From pregnancy to childbirth through nursing a newborn child, women are often expected to take the central role in creating new life by default. Similarly, when problems of infertility arise, the focus is often slanted toward females.
For several weeks, rumors have been circulating that a research group in China had performed the first targeted editing of DNA in human embryos. Today, the rumors were confirmed by the appearance of a paper in the journal Protein & Cell, describing genome editing performed at Sun Yat-sen University in Guangzhou, China. The paper shows that while the technique can work, it doesn't work very efficiently, suggesting there are a lot of hurdles between existing techniques and widespread genetic engineering of humanity.
